    Bad battery performance with connected standby enabled


    I have the surface pro 4 and i had as ive used it ive noticed bad battery life anywhere between 2 and a half hours or 3 hours of web browsing. So i was looking online and I saw that disabling connected standby might help. So i did and it increased my battery life to up to 4 hours. Is there any idea to why this may be as i really liked having this feature available.

    :)

    Can't enable Modern Standby

    You need an exclusively UEFI PC (without Legacy support) for Modern/Connected, at least it's what I've heard. I guess if that Z390 doesn't have it, I am not really expecting any consumer desktops to implement it, I assume it would require manufacturers to kinda rewrite their BIOS. It is also indirectly suggested on Anandtech that the feature depends on the onboard WiFi:

    Personally I love my Ethernet cables and 1Gbit speeds, and WiFi would be the last thing I'd do to my PC, but I would like to test this feature when I buy a new PC, since Z370 is clearly out of question. Considering that Z390 basically has onboard WiFi and Z370 doesn't , it further solidifies this as a potential WiFi only feature. Maybe it's possible for the PC to switch to WiFi for Connected Standby and then back to wire after it wakes up? That would be nice.

    Edit: there's also this:
    "Modern Standby is only available on some SoC systems. When it's supported, the system does not support S1-S3."

    Yeah... S3 is the "normal" standby. So if your firmware manufacturer supports that, it's bye-bye Modern? Ouch.
